IMPROVEMENT IN SIPHON-PUMPS.

Specification forming part of Letters Patent No. 136,809, dated March18, 1873.

To all whom it may concern: 1

Be it known that I, JAMES M. BOIS, of Salamanoa, in the county ofOattaraugus and State of New York, have invented certain Improvements inSiphon-Pumps, of which the following is a specification:

This invention relates to an apparatus designed for raising water bysiphonic action.

In the accompanying drawing, Figure I is a sectional elevation ofmyimproved siphonpump.

' A represents the reservoir containing the water; B, the short leg ofthe siphon; 0, its crown; and D, the long leg of the siphon. 12represents the valve or stop-cock arranged in the short leg of thesiphon at its lower end. 0 represents an opening provided in the crownof the siphon and closed by a screw-cap, c. 0 represents thedischarge-pipe arranged near the crown of the siphon in the leg D. It isprovided with a valve, f, arranged so as to prevent access of theexternal air into the said leg. 9 is a faucet arranged in acontinuation, g, of the discharge-pipe e. h is an automatic valvearranged in the long leg D of the siphon at its lower end so as toprevent the outflow of the water when closed. Its spindle works againsta spring, k, which throws the valve back into its open position. '5represents a stop-cock arranged in the lower part of the leg D, near thevalve h, so as to absolutely close the lower end of said leg whendesired.

The operation of my apparatus is as follows: The cocks b i being turnedso as to prevent passage of the water through their respective openings,and the opening 0 being opened, water is filled into the legs of thesiphon through the latter, and the air contained in the legs isexpelled, partly through the discharge-pipe e and partly through theopening 0. When the water commences to flow out of the discharge-pipe ethe faucet g is closed and the crown of the siphon filled, when the cap0 is again applied so as to close the opening 0 air-tight. Upon openingthe cocks b i and the discharge-faucet g, the water is first dischargedthrough the lower end of the leg D until its momentum closes the valveh, when. the water will raise thevalve f and discharge through the pipe0 and faucet g, thus relieving the valve h of excessive pressure andenabling the spring is to return the latter to its open position, whenthe same operation is repeated. lhe discharges of water through the pipe6 follow each other in such rapid succession that a comparatively steadyflow ot water is obtained.

1 claim as my invention- In combination with a siphon, the valves b hf,the cooks g i, and duct e, when arranged to operate as specified.
